MILK-BOTTLE CAP.

Application filed June 11, 1915.

To all whom it may concern.

presenting smooth inner and outer surfaces- Be it known that I, MAE S.GELLMAN BURR, a citizen of the United States, residing at Commack, inthe countyof Suffolk and State of New York, have invented certain newand useful Improvements in Milk-Bottle Caps; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention is animproved milk bottle cap, the object of theinvention being to pro vide an improved cap of this kind which isentirely sanitary, serves to protect. the mouth of the bottle bothinside and outside against the entrance of germs, dust and the like andwhich also enables the mouth of the bottle to be made without the usualgroove and shoulder on the inside, required by the caps heretoforecommonly in use, which groove and shoulder prevent the bottle mouth frombeing easily cleaned. p

The invention consists in a bottle cap hav ing an exterior flange to fitaround the mouth milk bottle having a mouth constructed in accordancewith my invention and provided with a sanitary cap also constructed inaccordance with my invention. Fig.2 is an inverted plan, partly insection, of the cap. Fig. 3 is an elevation','with the central portionbroken away, of the blank from which the collar or inner flange isformed.

The milk bottle l'-for use in connection with my improved cap 2 has aplain mouth 3 -l5, which are entirely unobstructed, the usual groove andshoulder on the inner side of the mouth being omitted, and this beinghighly desirable as such groove and shoulder render it difficult tothoroughly clean the bottle as the said shoulder forms a lodgment fordust, dirt and other impurities.

My improved cap may be made of paratiined paper or other suitablematerial, and

Specification of Letters ?atent.

\Vithin the scope of my invention the inner I flange or collar may beformed either iii-- tegrally with or separately from the cap. It

is here shown as formed separately from the cap and as being formed froma blank strip 8 of suitable length and width, having a tongue 9 at oneend and a slot 10 near the other end to receive the tongue and therebysecure the ends of the blank together and in overlapped relation, theblank strip being also provided at its outer edge, at suitable points,with tongues 11 which are passed through slits 19 in the cap and arebent inwardly on the outer side of the cap as shown in Fig. 1 and asindicated in dotted lines in Fig. 2.

Having thus described my invention, I claim:-

A bottle cap of the class described having an outer flange wall to fitaround the exterior of the bottle mouth and having a pair of spacedslits in the top thereof, and also having an inner wall or collar havinga pair of ears formed on its longitudinal edges at spaced distancesapart, said e rs adapted to fit up into the slots in the cap forsecurely holding the inner flange integral to the cap and at spaceddistance away from the outer flange wall of the cap, said inner flangeor collar being adapted to engage the inner face of the bottle mouth andprovided on one of its vertical ends with a locking tongue intermediateof its longitudinaledges and having a vertical slot fori'ned adjacentits opposite 'end intermediate the longitiulinal edges thereof, saidtongue adapted to fit in said slot for securely holding the inner flangeagainst the interior of the bottle mouth.
